Chapter 463 They are robbing!

When a flame is burning, it will simultaneously generate infrared radiation in three bands: 2.1μm, 2.7μm and 4.3μm. Using a two-color sensor can more accurately determine whether there is a fire.

In his previous life, Gao Zhendong had seen equipment that used 4μm-band infrared detectors to detect wildfires. But then again, if the wildfires were allowed to burn freely for several months or half a year like the United States and the Kangaroo Country did, it would actually make no difference whether there was detection or not.

Of course, in order to achieve the best effect, Gao Zhendong had seen in his previous life that our terminal-sensitive bombs have been solved very thoroughly, using three means: infrared, millimeter wave, and laser. That way, we can see clearly and lock firmly, but we don't have the conditions now.

There is a description that is very appropriate in engineering implementation.

You get what you pay for, you get two points for a dime, and you get three points for a dollar.

Gao Zhendong only wants one cent now, it’s not like he can’t use it.

Gao Zhendong said to Engineer Lu: "Boss Lu, we are the destroyers of design, not builders or saviors. Some of the requirements of the former are not as high as those of the latter."

To save people, a sufficient dose of medicine for the same disease cannot be taken twice in one dose, but to kill people, it is not a big problem to occasionally hit the same target twice.

After hearing what Gao Zhendong said, Engineer Lu laughed and said, "Mr. Gao, that makes sense, haha. What about this infrared detector that is sensitive to flames?"

Gao Zhendong knew that he had guessed it, and he also smiled: "Well, mercury cadmium telluride has a characteristic that its sensitive band can be obtained by adjusting the crystal component ratio."

Engineer Lu and Professor Luo both laughed. Mr. Gao was indeed very well prepared for his research project.

"Then I'll go back and simulate the control logic. If I can achieve the desired effect using logic control, that would be best."

Computers are the best means to implement algorithms and logic, but that does not mean that algorithms and logic must be implemented using computers, especially some simple control logic.

What Mr. Lu meant was to first see if the problem could be solved at the lowest possible cost without increasing the complexity of the equipment.

If it really doesn't work, consider asking Gao Zhendong for infrared materials.

Gao Zhendong nodded: "No matter what the results are, I will make a batch of suitable mercury cadmium telluride crystals for you first, so as not to delay your progress. Even if it can't be used here, it can be useful elsewhere, hehe."

Engineer Lu was very satisfied with the fact that he could get a lot of infrared sensitive materials for free, and he also proposed his other ideas: "I have analyzed that the lead sulfide sensor under refrigeration conditions seems to be able to basically meet the requirements. I will also try refrigerating lead sulfide. After all, it is cheap."

There are many times when more advanced means are used to solve problems, not because low-level means cannot solve the problem, but because advanced means can solve the problem better and more conveniently. However, this does not mean that advanced means must be used.

Gao Zhendong thought for a while and said, "Give it a try, but don't force it. If it's a little bit reluctant, just use mercury cadmium telluride. The extra money has been spent, so there's no need to be so stingy on detection."

Compared with whether to penetrate 80mm or 100mm, Gao Zhendong pays more attention to whether he can see and aim accurately. It is a good thing that Mr. Lu wants to make it cheaper, but Gao Zhendong still reminded him not to put the cart before the horse.

Engineer Lu nodded. "Okay, I'll be careful. If I have to pay too much other price, or the performance deviates even a little from the demand, I will still use mercury cadmium telluride."

After the meeting, Gao Zhendong left Beijing University of Technology. He came here today to attend classes, and he mixed classes with scientific research.

When Gao Zhendong was about to get in the car, Professor Luo was still reminding him: "Mr. Gao, don't forget to ask about the technology for me."

After returning to the Third Rolling Mill, Gao Zhendong called Mr. Xiang from the Institute of Chemistry.

The technology he thought of for Professor Luo that might be useful in increasing the quality and density of the charge was the twin-screw extruder that he had previously proposed to General Xiang.

The twin-screw extruder, or twin-screw extruder, is used by Mr. Xiang to extrude plastics, but its uses are far more than just extruding plastics.

Gao Zhendong knew about this thing from the propellant forming process. From this, he knew that this thing actually has a wide range of uses and is widely used in the forming of pyrotechnic products.

When General Xiang received the call and heard Gao Zhendong's request, he was very straightforward and immediately gave him the contact information of the comrade who was working on the twin-screw extruder.

One day later, Professor Luo received the information about the existing twin-screw extruder from Gao Zhendong.

"First, this thing is good. It has continuous discharge, less online material, high efficiency, and a mixing effect far superior to kneading, single screw and other methods. The material is evenly distributed and the particles are small..." After reading it, Professor Luo immediately went to the Defense Work Committee. The coordination of this thing depends on the Defense Work Committee. If improved properly, both the charge quality and charge density can be significantly improved.

Even a few points of improvement are very valuable. For the same charge, the charge density is directly linearly positively correlated with the armor-piercing power. If the density is increased by a few points, the armor-piercing power can theoretically be increased by a few points.

Uniform charging and fine particle size are beneficial to the full reaction of pyrotechnics and the generation of stable detonation waves, which can gradually increase the armor-piercing power.

Under the premise that resource conditions are determined, the increase in armor-piercing power is achieved by these comrades, little by little, from all aspects.

I really don't know where Mr. Gao found this thing. It really solves his problem.

He found out the answer to this question later, after the origin of the twin-screw was made public.

Somewhere in the northern Russian area, Comrade Sergeyev, who was in charge of non-military product trade with comrades in the south, was sulking as he looked at a product import application brought up by Petrovich.

"Comrade Petrovich, look at what bad news you've brought me. An operating system? What the hell is that? Why should we spend money on a program that has no clear, concrete purpose?"

"Comrade Sergeyev, this is what our computer experts specifically requested. I don't know how the comrades in the south recommended this to them, but they are like crazy, demanding that we must purchase enough installation media."

Just like how software was sold by floppy disks or CDs in the past, comrades from the Ministry of Foreign Trade are now selling tapes.

"Oh my god, look at this price, it's almost 20% of their expensive computer! It's robbery! Robbery! You know, selling a tape at this price is a gross violation of the rules of fair trade! We spent so much money and we can't even see a screw!"

This complaint is useless. This ratio is actually quite normal. In the late 90s and early 21st century, when the Win series of Giant Hardware sold for 1998 yuan, the mainstream computer price was only 10000 yuan. By this calculation, the price of our foreign trade department is actually very fair.

Petrovich shrugged. "Comrade Sergeyev, this is a technical product. This is how we sell it to them, and it's normal for them to sell it to us this way."

Sergeyev's eyes widened and he looked at him with a bull-like look: "My dear Comrade Petrovich, do you remember what I said before? I don't want to add to the list of high-tech products imported from the South! I don't want to!"

"Okay, Comrade Sergeyev, our scientist comrades will meet your requirements, but now, I think we have to meet their requirements first, right?" Petrovich said calmly and objectively, even a little teasing.

Petrovich, who finally got the signature, walked out of the office happily. Sergeyev looked at the forked tip of his pen because he used too much force and got angry: "Oh my God, there is really no good news! No, I need to add some strength!"

After saying that, he opened the drawer and took out a bottle.

Mr. Seine by the Seine River maintains his "elegance".

He smiled as he reviewed the memorandum of understanding between the two parties on the import and export of operating systems.

"Le Goff, I think we have to work harder. The Eastern Lion has impressed us again. Apart from the primary agricultural products from the colonies and the primary industrial products produced locally, we have nothing worth buying for them. This really frustrates me."

Le Goff said: "Mr. Senna, it's not that we don't have it, but the Technology Control Committee has strictly restricted the technology items we can use for transactions. In this case, I think you have done your best."

"Thank you. I am really happy with your words. Look, what they sell to us are computers, special steels, and software systems, and what we sell to them is food and urea... Mr. Le Goff, tell me, what is the meaning of us buying their urea steel and then selling them urea? "

Compared with us, the sources of chemical raw materials for Gaul at that time were much more extensive and in larger quantities, so it was not surprising that it could export urea to us.

Le Goff thought for a moment and rubbed his nose. "I guess at least we've increased our international trade. And our tax bureau has received taxes, hasn't it?"

Senna nodded: "Le Goff, you always make people happy. Okay, I'm not so sad anymore. Everyone has a bright future."

With a teasing tone, Senna signed the memo in his hand and handed it to Le Goff.

"Okay, go and do this. Turn the memorandum into a contract as soon as possible. Compared to the Citibank guys, at least the Orientals' prices are much fairer. Damn it! The Citibank guys don't even have this thing!"

The famous Unix appeared in the 70s. Even its predecessor, the Multics project, did not appear until 69. Before that, none of Citigroup's computer operating system projects could compare with the current operating system.

Thinking that the Citibanks were lagging behind the Orientals in this respect, Senna couldn't help but feel really happy. Thinking that John Bull didn't have any either, Mr. Senna felt as if everything was not unbearable.
